URL: https://github.com/apache/airflow/issues/27884
### Apache Airflow version
2.4.3
### What happened
As part of debugging some UI slowness, I have tried setting
AIRFLOW__WEBSERVER__WORKER_CLASS to gevent. However, this has broken the login
element:
`{views.py:659} ERROR - Error authorizing OAuth access token: maximum
recursion depth exceeded while calling a Python object

RecursionError: maximum recursion depth exceeded while calling a Python

Leaving the worker class to its default setting solves the issue, but I was
wondering what could have gone wrong here. This doesn't seem like an airflow
problem, rather a gunicorn one, but I would appreciate pointers if someone has
come across this before.
### What you think should happen instead
